GAS nooNoMIznn AND PURIFIER.

To all whom 'it may concern.'

Be it known that I, JOHN W. CARPENTER,

a citizen of the United States, and residentv of Salem, in the county of Harrison and State ofV West Vf'frgina, have invented certain new and useful Improvements in Gas Economizers and lurifiers, of which the following is a specification. l

My invention relates to improved devices for purifying 1gas and for preventing a wasteful use thereof, and it consists of the constructions, combinations and arrangements of parts herein described and claimed.

. An obj ect lof my invention, as stated above,

is to provide a device which will remove from the gas such impurities as particles of sand, dirt, or rust and to provide means whereby they may be expelled entirely from the device.

A further object-of my invention is to provide means for decreasing theexcess flow of and thereby saving the gas and leconomiizing in the use of the same.

Further objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out m the appended claim.-

-My invention is illustrated in the accompanying drawings, in whiclr- Figure 1 is a central section through the device, and Fig. 2 is a section at right angles to that in Fig. 1' along the central portion of the device, certain parts being broken away in order to show the construction.

l'n carrying out my invention, I provide two hemispherical shells 1 and 2 which are preferably of metal and which form the main part of the casing. To the central portion of the shell 1 is secured an inlet pi e 3, the latter being screwed into the shel, as

clearly shown inthe drawing. On the endA of the pipe 3, within the shell 1, is secured a cap 4 which is perforated at 4a along its periphery so as to permit the exit of gas. The shell 1 is also provided with a curved fiange l'x extending inwardly as shown in Fig. 1. The shell 2 has a pipe 5 whichis secured into its central portion and is for the exit of the gas.

vEach of the shells 1 and 2, has an external flange 1 and 2', respectively, and these fianges are arranged to register so as to be secured by means of the bolts 6. Between the flanges is secured a central perforated metal disk7 and on either side of the disk are .the flexible membranes 8 and 9. The

latter are preferably hog-skin but may be made of other suitable material for straining the gas. The edges of these disks areA vextended over so as to register with the flange portions 1 and A2 of the shells 1 and 2, andthe membrane together with the central perforated disk 7 are held together by means of the bolts 6. Between the membrane 8 andthe disk 7, there may be placed a leather' spacer 10 or the device may be withoutv the spacer, if desirable.

The section 1 of the casing is provided with a pet-cock l2, situated near the inlet plpe 3.

rom the foregoing description of the device, the operation thereof may be readily understood.

The device is intended to be used prefer- It may be inserted in the-eircu1t near the meter and preferably on the opposite side of the meter from the gas mam. The 'gas and*4 air pass through the meter and on into the inlet pipe 3. From thence it passes `through the perforations 4 into the lower chamber 1. It will be noted that these perforations laA are in the side and not in ,the end of the cap f1. The dirt which is carried with the gas through the perforations is directed into the groove 1y between the body portion of the shell 1 and the fiange l". Thence it drops by gravity into the bottom of the shell. This prevents the clogging yof the pores of the diaphragm by particles which might be projected directly against Patented N ov. 1,l 1910.`

fill

the diaphragm if the openings were in the end of the cap. The gas passes through the central opening between the edges of the fiange 1. Here it meets the resistance of the first diaphragm, passes through the perforations in the disk 7 and on through the Second diaphragm, and thence throu `h the exit. The dirt or rust is filtered out y the first diaphragm and drops down into the lower part of the chamber 1, from hence it may be blown out by opening the pet-cock 12. fi further saving by the use of the economizer and purifier 1s found in the mantles,

as no particles of sand, dirt, or rust can Imssv the economizer and purifier to destroy the same.

u ln` the use of the economizer, it will be seen that nothing but gas is consumed. Aside from the saving to rnantles, it saves the burners in this: that by the use of the gas econoinizer and purifier the 0fas comes to the lights filtered, thereby avoiding the necessity of?l frequent boiling vand cleaning of burners, screwed to the end of said inlet ipe and being secured between the abutting anges and tends to lessen the chances of explosion. provided with perforations in the slde there- 15 Iclaim: l of the hemispherical section bearing the" In a gas plirier and economizer, a casing inlet pipe also being provided with an incomprising two hemispherical sections prowardly curved fiange directed toward the vided with peripheral anges, a perforated inlet pi e, a'coek secured in said section near metal disk, aresllient membrane'on each side said 1n et pie and an exit pipe from the 20 of said disk,I said disk and said membraner other hemisp erica] section.
